Pull Math Answer

[Medic873]

Okay im using a website called wolframalpha.com Im sure you have heard of it.. Dose math problems online well I already have the code to submit a math question but Im not sure what to do to harvest the answer from the website here is my current code.

#include <IE.au3>

$Question = inputbox ("Question", "What is the math problem you would like our software to solve.");

$oIE = _IECreate ( "http://www.wolframalpha.com/input/?i=" & $Question )
_IELoadWait ($oIE);Waits for webpage to load
;then copy answer to $Answer
msgbox (1,"Answer", "The answer is " & $Answer);

but my problem is pulling the answer how do I do this....

[Medic873]

see first of all it puts it in a difrent spot every time it seems like a algebra problem with be called a solution because of many mathmatical reasons and a 2+2 problem with be called answer how can I pull all these and display them because they are also images so I cant copy them so how can I take the image url and display it in a msgbox

[Medic873]

I am also willing to use a diffrent website or whatever might finish this if you can find a script out here I am more then pron to use it I have been looking for the past hour or so and havnt found nothin

I almost dont want to respond because you have bumped twice in an hour (try the edit button), nonetheless.

By subbing out the math characters with the HTML codes it seems to have the desired result returned first. and capturing that is easy enough. the example below performs the magic of addition.

#include <INet.au3>

$Question = inputbox ("Adding Machine", "What is the math problem you would like our software to solve.");

$URL = StringReplace ($Question , "+" , "%2B")

$Source = _inetgetsource ("http://www.wolframalpha.com/input/?i=" & $URL)

$AnswerArray = StringRegExp ($Source , 'id="i_0200_1" alt="(.*?)"' , 1)

msgbox (0, 'Answer' , $AnswerArray[0])

Okay sorry about the bumping guess I should have edited it rather then post agian but enter something like 4x=4 and it returns a error how can I fix that.

Okay sorry about the bumping guess I should have edited it rather then post agian but enter something like 4x=4 and it returns a error how can I fix that.

Maybe try the obvious thing.. like..

#include <INet.au3>

$Question = inputbox ("Adding Machine", "What is the math problem you would like our software to solve.");

$URL = StringReplace ($Question , "+" , "%2B")

$Source = _inetgetsource ("http://www.wolframalpha.com/input/?i=" & $URL)

If StringInStr($source, "Wolfram|Alpha doesn't know how to interpret your input.") Then
    MsgBox(0,"", "This program doesn't know how to interpret your input.")
Else
    $AnswerArray = StringRegExp ($Source , 'id="i_0200_1" alt="(.*?)"' , 1)

    msgbox (0, 'Answer' , $AnswerArray[0])
EndIf

[iamtheky]

just start handling the different characters

- such as the equal sign which is %3D

(edit::looks like it does tolerate '=' just fine tho)

and handling the results

- since the first return of 4x=4 is a graph stringregexp does not return an array, so if an array is not returned grab the second answer and return it.

#include <INet.au3>

$Question = inputbox ("Adding Machine", "What is the math problem you would like our software to solve.");

$URL = StringReplace ($Question , "+" , "%2B")

$URL1 = StringReplace ($URL , "=" , "%3D")

$Source = _inetgetsource ("http://www.wolframalpha.com/input/?i=" & $URL1)

$AnswerArray = StringRegExp ($Source , 'id="i_0200_1" alt="(.*?)"' , 1)

if not isarray($AnswerArray) Then

$AnswerArray = StringRegExp ($Source , 'id="i_0300_1" alt="(.*?)"' , 1)

Endif

msgbox (0, 'Answer' , $AnswerArray[0])

That doesn't solve my issue first of all I dont want it to tell the user that it couldn't solve it cause it can its just under a different web variable because its a solution not a answer.

Second that still returns a array error.lol

I just need it to find this url

Okay thank you im going to try and add some stuff and I will ask for help if need thank you so much I really have trouble working the inetget commands and this is has helped me greatly

[Tvern]

I just need it to find this url

http://www3.wolframalpha.com/Calculate/M...5?MSPStoreType=image/gif&s=33

if you do the math problem 2x=4

Then you just need to change the regex in the example iamtheky posted. like this:

#include <INet.au3>

$Question = inputbox ("Adding Machine", "What is the math problem you would like our software to solve.");

$URL = StringReplace ($Question , "+" , "%2B")

$URL1 = StringReplace ($URL , "=" , "%3D")

$Source = _inetgetsource ("http://www.wolframalpha.com/input/?i=" & $URL1)
$AnswerArray = StringRegExp ($Source , 'src="(.*?)" id="i_0200_1"' , 1)
if not isarray($AnswerArray) Then
$AnswerArray = StringRegExp ($Source , 'src="(.*?)" id="i_0300_1"' , 1)

Endif
msgbox (0, 'Answer' , $AnswerArray[0])

That still returns a array error.lol

Why is that a problem?

You should probably sign up for a free Wolfram ID, so you can use their interactive API though.
